i wonder, i am curious, how did first lady michelle ng obama respond to the news when you talk to her or this was brought to her? >> one of the challenges for those of us writing about the first lady is she is not doing any book interviews at all. i didn't get to talk to her about this but when the article came out, her husband's press secretary was asked about it and said she sounded fascinating. i know her family finds it fascinating and i think it was something they simply -- simply didn't know about. i briefed her staff along the way as i was doing my research and gave her and members of the family, i hope she find it fascinating. >> one thing i did read in the new york times when your article was published, she did have a positive reaction to if, and at some point she even traveled to africa with the children to see the places where the slaves were housed or africans when they were imprisoned warehouse before they were taken in the middle passage and across the sea to the americas. it was very interesting that she was curious to follow her roots all the way to africa as well. you
